Detailed Description of the Invention

[0001]

[Industrial application] The present invention is mainly used in large-scale underground facilities, large-scale building groups such as department stores and hospitals, and facilities used by physically handicapped persons such as the elderly and hearing impaired, in case of disaster. The present invention relates to a light traveling type evacuation guidance device that guides a person in a safe direction.

2. Description of the Related Art The applicant has previously devised an optical traveling type evacuation guidance system which is a drastic improvement of the emergency exit lighting system (Japanese Patent Application No. Hei 3).
-281663). The light traveling type evacuation guidance device is shown in FIG.
Shown in FIGS. FIG. 14 is a block diagram of this device, FIG. 15 is a schematic circuit inside the lamp (10), and FIG. 16 is a wiring diagram between the lamps (10). Describing the operation based on these figures, a fire occurs, the automatic fire alarm equipment receiver (1) is activated, and the signal is transmitted to the guide signal device (3) via the transfer device (2). Fire signal generator (4) with a built-in guide light control device (C2) from the guide light signal device (3)
Fire information will be sent to. The fire signal generator (4) determines a taxiway suitable for the fire information, and outputs a pulse signal according to the determined taxiway to generate a pulse signal (20).
Issue a command to. Each lamp (10) has a counter (21)
Is provided and starts to send the UP / DOWN switching signal of the counter output from the pulse generator (20) and the clock pulse for operating the counter (21) to each lamp (10). An address is set to each of the lamps (10) by an address setting circuit (14), and a pulse sent from the pulse generator (20) and an UP / DOWN switching signal (2) that determines the traveling direction of the light. It has an address comparison circuit (22) for comparing with the count value of the counter (21) which operates according to the direction, and when it matches, it is lit up. Pulses are sent from the pulse generator (20) one after another, and the contents of the counter (21) are changed, whereby the lamps to be turned on are switched and a flow of light is produced to induce the light. In this device, as shown in FIG. 16, the power supply line 2 is connected to each lamp (10).
Books (31), (32), pulse signal lines (34) and UP
It is necessary to connect a total of four / DOWN switching lines (35) each. Compared to the traditional fixed type green emergency exit lighting device, this method has a much advanced induction function, but compared to this idea, there are more wires, so construction costs and construction errors Is a disadvantage from. In addition, since a counter is used, the guidance direction is UP
/ DOWN is small in two directions, and when the counter malfunctions and the light traveling is disturbed by further disturbance, the counter has to be reset, and when the device is continuously operating, the disturbance of the light traveling continues forever, There was a problem that the error was accumulated.

[0003]

This applies not only to the light traveling type but also to the evacuation guidance apparatus in general. However, malfunction may possibly cause human life, and it is preferable to suppress occurrence as much as possible. In addition, it is important that the person can make a detailed guidance in response to the situation so that the person does not make a mistake in the judgment, and that it can be economically realized because it is widely used. The present invention is strong against disturbance, and even in the case of a momentary malfunction, it ends only in one cycle of blinking, returns to normal in the next cycle, no error is accumulated, and the number of wirings is reduced.
Moreover, it is an object of the present invention to provide an optical transmission type evacuation guidance device that is easy to set and change the traveling direction of light, has large flexibility, and can perform complicated guidance.

[0004]

In the device of the present invention, the guide light control device (C) and each lamp (10) are connected by two power lines (31) and (32), and each lamp ( In order to control the blinking of 10), a lamp control signal generator (5) capable of sending a control signal including an address at an arbitrary timing and a signal including the control signal to the power supply lines (31) and (32). Each lamp (10) has a modulation section for superimposing, and a demodulation section for demodulating a control signal from a signal superimposed on the power supply, and an address included in the demodulated control signal and an address previously assigned to each lamp match. , And a control circuit (13) for judging the disagreement and controlling blinking of the lamp (16) according to the judgment result. Or two power lines (31), (32)
And one control signal line (33) connect the guide light control device (C1) and each lamp (10), and each lamp (10)
In order to control the blinking of the lamp, a lamp control signal generator (5) for sending a control signal including an address at an arbitrary timing is provided, and each lamp (10) is guided by a control signal line (33). A lamp control for determining whether the address included in the control signal output from (C1) matches the address assigned to each lamp (10) in advance or not and controlling the blinking of the lamp (10) according to the determination result. It comprises a circuit (13).

[0005]

When the fire signal control device (4) receives the fire signal, it determines the evacuation route and transmits it to the lamp control signal generator (5). The lamp control signal generator (5) generates a control signal including the address of the lamp corresponding to the determined evacuation route and transmits it to the modulator (6). The modulator (6) superimposes the modulated wave modulated by the control signal on the power supply line and sends it to each lamp (10) through the two power supply lines (31) and (32). In each lamp (10), the control signal receiver (11) receives and the demodulator (12) demodulates the control signal. An address is included in the demodulated control signal, and this address is compared with the address of each lamp (10), and when the addresses match, the lamp (16) is driven. The lamp control signal generator (5) sequentially generates an address pattern capable of achieving a desired guidance direction based on the fire information, and controls blinking of each lamp (10) to create a light flow. Alternatively, the guide light control device (C1) and each lamp (10) are connected by two power lines (31) and (32) and one control signal line (33) to connect each lamp (10). In order to control blinking, a control signal including an address is output from the lamp control signal generator (5) at an arbitrary timing, and a control signal line (3
3) through the lamp control device (1) of each lamp (10) directly
It is transmitted to 3). The address included in the control signal output from the guide light control device (C1) and each lamp ((1
Matching or non-matching with the address previously assigned to 0) is determined, and blinking of the lamp (10) is controlled according to the determination result.
Similarly to the above, patterns are sequentially generated to control the blinking of each lamp (10) to create a light flow.

[0006]

In each lamp (10), the address data (18) included in the control signal is compared with the own address specified for each lamp (10) at each instruction cycle. Since the flashing of each lamp (10) is determined, even if there is a malfunction in the lamp (10), the malfunction ends only in that cycle, and the error is not accumulated and the reliability and safety are high. . The control signal line can be eliminated or the number of wires can be reduced to one, and construction costs and mistakes can be reduced. Moreover, by changing the content of the address data (18) sent at each timing, the blinking lamp (10) can be freely set without changing the existing lamp (10).
The degree of freedom in the traveling direction of light is great, and the guiding direction is flexible.
